Chapter 6 Page 164 Questions 1-8

Question 1: When is an atom least likely to react?

Question 1: Answer When is an atom least likely to react?

When the highest energy level of an atom is filled with electrons

Question 2: Describe one way an element can achieve a stable electron configuration?

Question 2: Answer Describe one way an element can achieve a stable electron configuration?

Through the transfer of electrons between the atoms

Question 3: What characteristic of ionic bonds can be used to explain the properties of ionic compounds ?

Question 3: Answer What characteristic of ionic bonds can be used to explain the properties of ionic compounds ?

The strong attraction among ions within a crystal lattice

Question 4: Use Ionization energy to explain why metals lose electrons more easily than non metals ?

Question 4: Answer Use Ionization energy to explain why metals lose electrons more easily than non metals ?

Metals have a lower ionization energies than non-metals. The Lower the ionization energy , the easier it is to remove an electron from an atom.

Question 5: Why is a rock salt crystal likely to shatter when struck ?

Question 5: Answer Why is a rock salt crystal likely to shatter when struck ?

When ions with the same charge are pushed close together, they repel one another

Question 6: What will the ratio of ions be in any compound formed from a group 1A metal and a group 7A non-metal ?

Question 6: Answer . What will the ratio of ions be in any compound formed from a group 1A metal and a group 7A non-metal ?

The ratio will be one to one because a group 1A metal loses one electron to achieve a stable electron configuration.

Question 7: Why do ionic compounds include at least one metal?

Question 7: Answer Why do ionic compounds include at least one metal?

One element in an ionic compound must form cations, but non-metals tend to form anions.

Question 8: Based on their chemical formulas which of these compounds is not likely to be an ionic compound : KBr , SO2, or FeCl3 ? Explain your answer.

Question 8: Answer SO2 because sulfur and oxygen are both non-metals and unlikely to form cations
